Time Series & Playgrounds in Forward¶
The browser experience from Classic is back, rebuilt and improved for Forward.

Sometimes you just need to run a quick query. Check a chart. See what's in a table.
Playgrounds is a SQL editor in the browser. Write SQL, hit run, see results. You can debug production endpoints with different parameter values, test queries before pushing, or jump in to help a teammate with a gnarly join. Keep your work private or share it with your Workspace.
Time Series visualizations are back with their own spot in the navigation. Pick a Data Source, choose a date column, see records over time. Open any Observability chart to explore it further. Zoom in. Share with your Workspace colleagues.

Both features work in Tinybird Cloud, in branches, and with Tinybird Local.
Resumable NDJSON imports¶
NDJSON imports from URLs now support HTTP Range headers. If a download is interrupted, the import resumes from where it left off instead of starting over. Useful for large files on unreliable connections.
Bug fixes and improvements¶
- [Forward]: Fixed false dependency detection when deleting a Data Source that shares its name with a shared Data Source.
- [CLI]: Fixed false circular dependency detection when a shared Data Source has the same name as a local Pipe. Requires CLI 6.0.1.
Deprecation notice¶
Starting February 15, 2026, replace operations via the /v0/datasources/ endpoint submitted with an empty file will no longer be supported. After this date, these requests will return an HTTP 400 Bad Request with the error message: Replace operations with empty data are not supported.
